Greeting htc,
I am a auto tech for a independent garage in Ohio. We currently have a 03 Ram 1500 5.7 Hemi in our shop. The truck came in with a customer complaint of not running right, hard brake pedal, and inoperative 4x4. Upon inpection of the truck I found that the Intake manifold was broken. And when I pulled it off the engine I found that not only was it broken, but that it had actually blown the the intake into three separate pieces. The seam that goes around the side was blown apart. Then the bottom half was also split in two pieces. My concern is what caused this to happen? I pulled the valve covers off, all the valve springs are intact. I turned the engine over by hand everything moves the way it should. The valves are all sealing. I have good cranking compression. The only other thing that I found was the spark plugs on the #1 cylinder were bent flat, as if something had pinched between them and the piston. I do have the same good compression on the #1 cylinder that I do on the other cylinders.
Is there any issues with the intakes on these engines? Is there something that I am over looking? Could it be that the engine jumped time? ON a side note I did drive the truck into the shop. It would run with the intake blown apart.
I am putting this truck back together tomorrow and I don't really want the same thing to happen to the new intake manifold. Any ideas of what may have caused this to happen? I do have pics of the old intake if anyone is interested I can post them. lmk
Thanks in advance for you help
